4625 *
bf79451e
JG		 4626 * The READ index maps to the first position that the firmware may be writing
4627 * to -- the driver can read up to (but not including) this position and get
4628 * good data.
43f66a6c
JK		 4629 * The READ index is managed by the firmware once the card is enabled.
4630 *
4631 * The WRITE index maps to the last position the driver has read from -- the
4632 * position preceding WRITE is the last slot the firmware can place a packet.
4633 *
4634 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
bf79451e 4635 * WRITE = READ.
43f66a6c 4636 *
bf79451e 4637 * During initialization the host sets up the READ queue position to the first
43f66a6c
JK		 4638 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4639 *
4640 * When the firmware places a packet in a buffer it will advance the READ index
4641 * and fire the RX interrupt. The driver can then query the READ index and
4642 * process as many packets as possible, moving the WRITE index forward as it
4643 * resets the Rx queue buffers with new memory.
bf79451e 4644 *
43f66a6c 4645 * The management in the driver is as follows:
bf79451e 4646 * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
43f66a6c 4647 * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
bf79451e 4648 * to replensish the ipw->rxq->rx_free.
43f66a6c
JK		 4649 * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
4650 * ipw->rxq is replenished and the READ INDEX is updated (updating the
4651 * 'processed' and 'read' driver indexes as well)
4652 * + A received packet is processed and handed to the kernel network stack,
4653 * detached from the ipw->rxq. The driver 'processed' index is updated.
4654 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 4655 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
4656 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
43f66a6c
